Why does the data type code show as "A" in T4 XML file for Cancelled

E1 9.2 Canadian Payroll

Hello,

when a 2023 T4 was cancelled the code in the XML file is showing as "A". Should that not be a "C"?

The year end ID was archived and the required T4 was cancelled. The processing options on the R89772001X were set with the Data Type Code = C. The XML file was created and contains the one cancelled T4 so the process recognized the Data Type but the <rpt_tcd> in the XML is showing as "A" as well as in the R77417 report (<rpt_tcd>A</rpt_tcd>)

Is this correct? CRA documentation shows that the code should be either O, A, or C.
